It always takes more than a year or two before you can really begin to get a feel for what a draft class really looks like, whether you’re talking about league-wide or for a specific team. Immediate post-draft grades pretty regularly prove to be utterly worthless and far from accurate a short time down the road.
That is why I do appreciate and place some value in those who put in some effort to do things like redraft exercises for other classes later on. Pro Football Focus recently did a redraft exercise for the 2017 NFL Draft class, which has given players three years to get on with their NFL careers, typically a pretty safe period of time, limiting themselves to the first round.
